Albums of recorded music were developed in the early 20th century, first as books of individual 78rpm records, vinyl LPs are still issued, though in the 21st century album sales have mostly focused on compact disc and MP3 formats. The audio cassette was a format used from the late 1970s through to the 1990s alongside vinyl, an album may be recorded in a recording studio, in a concert venue, at home, in the field, or a mix of places. Recording may take a few hours to years to complete, usually in several takes with different parts recorded separately. Recordings that are done in one take without overdubbing are termed live, the majority of studio recordings contain an abundance of editing, sound effects, voice adjustments, etc. With modern recording technology, musicians can be recorded in separate rooms or at times while listening to the other parts using headphones. Album covers and liner notes are used, and sometimes additional information is provided, such as analysis of the recording, historically, the term album was applied to a collection of various items housed in a book format.

Pop music
–
Pop music is a genre of popular music that originated in its modern form in the United States and United Kingdom during the mid 1950s. The terms popular music and pop music are used interchangeably, although the former describes all music that is popular. Pop and rock were synonymous terms until the late 1960s, when they were used in opposition from each other. Although pop music is seen as just the singles charts, it is not the sum of all chart music. Pop music is eclectic, and often borrows elements from other such as urban, dance, rock, Latin. Identifying factors include generally short to medium-length songs written in a format, as well as the common use of repeated choruses, melodic tunes. David Hatch and Stephen Millward define pop music as a body of music which is distinguishable from popular, jazz, according to Pete Seeger, pop music is professional music which draws upon both folk music and fine arts music. Although pop music is seen as just the singles charts, it is not the sum of all chart music, the music charts contain songs from a variety of sources, including classical, jazz, rock, and novelty songs. Pop music, as a genre, is seen as existing and developing separately, pop music continuously evolves along with the terms definition. The term pop song was first recorded as being used in 1926, Hatch and Millward indicate that many events in the history of recording in the 1920s can be seen as the birth of the modern pop music industry, including in country, blues and hillbilly music. The Oxford Dictionary of Music states that while pops earlier meaning meant concerts appealing to a wide audience. Since the late 1950s, however, pop has had the meaning of non-classical mus, usually in the form of songs, performed by such artists as the Beatles. Grove Music Online also states that, in the early 1960s pop music competed terminologically with beat music, while in the USA its coverage overlapped with that of rock and roll. From about 1967, the term was used in opposition to the term rock music. Whereas rock aspired to authenticity and an expansion of the possibilities of music, pop was more commercial, ephemeral. It is not driven by any significant ambition except profit and commercial reward, and, in musical terms, it is essentially conservative. It is, provided from on high rather than being made from below, pop is not a do-it-yourself music but is professionally produced and packaged. The beat and the melodies tend to be simple, with limited harmonic accompaniment, the lyrics of modern pop songs typically focus on simple themes – often love and romantic relationships – although there are notable exceptions

Record producer
–
A record producer or music producer oversees and manages the sound recording and production of a band or performers music, which may range from recording one song to recording a lengthy concept album. A producer has many roles during the recording process, the roles of a producer vary. The producer may perform these roles himself, or help select the engineer, the producer may also pay session musicians and engineers and ensure that the entire project is completed within the record companies budget. A record producer or music producer has a broad role in overseeing and managing the recording. Producers also often take on an entrepreneurial role, with responsibility for the budget, schedules, contracts. In the 2010s, the industry has two kinds of producers with different roles, executive producer and music producer. Executive producers oversee project finances while music producers oversee the process of recording songs or albums. In most cases the producer is also a competent arranger, composer. The producer will also liaise with the engineer who concentrates on the technical aspects of recording. Noted producer Phil Ek described his role as the person who creatively guides or directs the process of making a record, indeed, in Bollywood music, the designation actually is music director. The music producers job is to create, shape, and mold a piece of music, at the beginning of record industry, producer role was technically limited to record, in one shot, artists performing live. The role of producers changed progressively over the 1950s and 1960s due to technological developments, the development of multitrack recording caused a major change in the recording process. Before multitracking, all the elements of a song had to be performed simultaneously, all of these singers and musicians had to be assembled in a large studio and the performance had to be recorded. As well, for a song that used 20 instruments, it was no longer necessary to get all the players in the studio at the same time. Examples include the rock sound effects of the 1960s, e. g. playing back the sound of recorded instruments backwards or clanging the tape to produce unique sound effects. These new instruments were electric or electronic, and thus they used instrument amplifiers, new technologies like multitracking changed the goal of recording, A producer could blend together multiple takes and edit together different sections to create the desired sound. For example, in jazz fusion Bandleader-composer Miles Davis album Bitches Brew, producers like Phil Spector and George Martin were soon creating recordings that were, in practical terms, almost impossible to realise in live performance. Producers became creative figures in the studio, other examples of such engineers includes Joe Meek, Teo Macero, Brian Wilson, and Biddu
